What is TPS in performance testing?
This measure is most often characterized as TPS (transactions per second), TPM (transactions per minute), TPH (transactions per hour), or TPD (transactions per day). Throughput is not the inverse of latency. What is response time in performance testing? Response Time measures the performance of an individual transaction or query.
What is tph and how is it defined?
TPH is defined by the analytical method that is used to measure it. Conventional TPH measurement techniques quantify only those hydrocarbons that are extracted by the particular method.
What is throughput in performance testing?
Throughput is a rate. A rate is the measure of how many actions are completed in a unit of time. This measure is most often characterized as TPS (transactions per second), TPM (transactions per minute), TPH (transactions per hour), or TPD (transactions per day). Throughput is not the inverse of latency. What is response time in performance testing?
Is it possible to measure total amount of TPH at site?
However, it is useful to measure the total amount of TPH at a site. TPH is a mixture of chemicals, but they are all made mainly from hydrogen and carbon, called hydrocarbons. Scientists divide TPH into groups of petroleum hydrocarbons that act alike in soil or water. These groups are called petroleum hydrocarbon fractions.
What is throughput in performance testing?
To recap: Throughput is a key concept for good performance testers to understand, and is one of the top metrics used to measure how well an application is performing. I've also written some other post on other concepts that a performance test engineer should know about:
How many cars can Joe's gas station fill?
Let’s call this gas station “Joe’s Gas,” and envision that it only has three gas pumps. Naturally, if we have three gas pumps and three cars, it follows that Joe's attendants can only fill up three cars per minute. So, if we were to fill out a performance report for Joe's gas station, it would show that Joe’s throughput is three cars per minute.
What is throughput in testing?
Basically, “Throughput” is the amount of transactions produced over time during a test. It’s also expressed as the amount of capacity that a website or application can handle. Also before starting a performance test it is common to have a throughput goal that the application needs to be able to handle a specific number of request per hr.
How long does it take a gas station attendant to fill up a car?
Let’s also say that it always takes the gas attendant just one minute to fill up any car, no matter how big it is or how low the car's gas tank is.
Why do gas pumps have queues?
As more vehicles enter the gas pump line they are required to wait, thus creating a queue.
What is TPS in a server?
Transactions per second or TPS shows the number of transactions sent by the users in one second. TPS is one of the key metrics of non-functional requirement which helps to set the expected load on the server. The bigger unit of TPS is Transactions per hour (TPH) which represents the transaction rate at an hourly basis.
What is a scenario in business?
A scenario is a window where a performance tester defines no. of users, test duration, Vuser running pattern, etc. along with business processes
What is response time?
Note that the Response Time is the sum of Network Latency and Server Processing Time.
What is throughput in JMeter?
As per Apache JMeter, throughput is the number of requests sent per unit of time by JMeter to the server.
What is pacing in a performance test?
Pacing helps to achieve the required TPS (transactions per second) in a performance test.
What is a transaction in web design?
A transaction is a group of requests belong to a particular page. Ideally, each user action has one separate transaction so that response time can be measured individually. Although one transaction can also have multiple user actions. It totally depends on what to measure.
What is network latency?
Network Latency represents the time taken by the network to transfer the data from one end to another. A channel or network adds some delay while transferring the data between Client and Server. The faster a network, the lesser network latency. Therefore network latency plays an important role in performance testing.
What is Performance Testing?
Performance testing is a testing technique that determines the speed, scalability, and stability of an application under a given workload. It helps to ensure the quality of the software and makes the application ready to be released into the market.
What is scalability testing?
Scalability testing - The main objective of scalability testing is to determine whether the application can scale up effectively in the event of user overload. This testing also helps you to plan capacity addition to your application for the future.
Why is performance testing important?
Performance testing validates multiple factors of an application to ensure its reliability. It is an important factor for all organizations to handle high traffic loads and overcome other performance problems. As such the demand for testing professionals with these skills are in high demand.
What is web load?
WebLoad - WebLoad is used for web and mobile load testing. It combines all the performance testing components into a single process for the verification of web and mobile applications.
What is volume testing?
Volume testing - The main objective of volume testing is to check the performance of the application in different database volumes. The behavior of the application is monitored by populating varying volumes of data into the database.
What is JMeter?
JMeter - JMeter is an open-source, cloud-based testing tool that helps you to analyze and measure the performance of web applications.
What is the purpose of stress testing?
Stress testing - The main objective of stress testing is to identify the main breaking point of a software application. This is done by testing the application under extreme workloads to gauge its performance under high traffic or data processing.
What Does Performance Testing Check in any Software?
Under such situations, performance testing process actually measures the Speed, Scalability, Reliability, Robustness and Stability of the application when the system is tested for varying loads of users. Performance testing procedure in the cloud also lets you maximize your returns by utilizing cost-effective means of scalable testing applications.
What are the Different Types of Performance Testing?
Load testing: Load testing is performed to validate the system (application under test) performance under normal (usually around 70% of peak user load) and peak user load. This type of test helps us to tune the system and finalize the baseline. Companies should adopt load testing as a part of their software development life cycle (SDLC).
What is capacity testing?
Capacity testing: With this type of testing, also known as scalability testing, helps to identify the actual number of the users that the system can support with current hardware capacity
What is a spike test?
Spike testing: This is a subset of stress testing and it analyzes the behaviour of the system by suddenly varying the number of users and it also checks if the system is able to support such situations efficiently
What is the breaking point of a system?
The breaking point can be defined as a load at which either the response time degrades beyond 10% or transactions start falling by more than 5%. Usually, we subject the system to up to 2x of peak user load during the stress tests
What is loadninja used for?
LoadNinja helps the teams to increase the test coverage without compromising on the quality. Also, it removes the efforts which are necessary for script translation, dynamic correlation, and script scrubbing. 2. JMeter: JMeter is an open-source tool used for running performance and load tests.
What is the purpose of a speed test?
Speed: The system is tested and evaluated to check the speed with which it responds
